It is configured as follows . As shown in FIGS. 1, 2 and 8, this rice transplanter has an auxiliary marker (79) in addition to the left and right muscle markers (77) and side markers (78). The base end of the marker (79) is supported on the marker mounting base (80) of the base frame (3) via a mounting screw (81) so as to be freely adjustable in protruding length and horizontally rotatable. Is arranged along the upper part of the adjacent strip obliquely forward of the body to run the body. In this embodiment, the wheels (7) and (8) are rolled and run while the seedling mounting table (13) is reciprocally slid left and right. The seedlings of the mat (13) are divided by the planting claws (14), taken out one plant at a time, and are sequentially planted. The unit clutch (48) of the planting case (17b) on the left side is now disengaged. In the case of performing a three-row planting operation with the planting claws (14) of the remaining planting cases (17b) and (17c), when the clutch lever (57b) is turned off, the unit clutch of the planting case (17b) is released. (48) is turned off to stop driving the left and right planting claws (14) (14) attached to the case (17b), and at the same time, the seedlings are moved by the planting claws (14) (14). For two rows of picking platform (13) for picking The vertical feed tube axis (75) clutch also by rotation of the clutch (68) (62a)
The drive is stopped by the disengagement of (62b),
The vertical feeding of the seedling by each star wheel (43) is interrupted. As a result, even if the driving of the planting claws (14) is stopped, the inconveniences such as the vertical feeding of the seedlings on the seedling mounting table (13) corresponding to the stop and the deformation of the seedling mats are eliminated, and the seedling mats are eliminated. Is always accurately and safely held on the seedling stand (13). Therefore, good planting work can always be carried out without causing a lack of stock or a poor planting posture when planting is restarted. As is apparent from the above embodiments, the present invention provides a unit for stopping the planting claws (14) for each planting unit.
